Abstract

By optimizing the traction force of each load node bending moment matching blade loading process, a full-size set of frequency control of motor speed electro-hydraulic drive static test system has been researched. Deviation at each node load force as the input, the frequency for each load point of the output control, the BP (back propagation) neural network PID (proportion-proportion-differentiation) control algorithm was designed. Value output deviation value into PID controller operation frequency, deviation value and frequency value on-line adjustment of BP network, at the same time get the PID parameter setting, reduced the number of each node traction coupling, realized the node coordinate loading full size. Experimental results show that the control algorithm to solve more coupling and loading in the process of loading point traction can maintain smooth, coordinate change, have stronger anti-jamming adaptability, meet the requirement of the static loading test for blades of wind power.
